Definitions

  • the invention relates to an injection cooler for Temperature control of superheated steam according to the preamble of Claim 1.
  • Steam coolers are different between steam systems Temperature levels used to at different Operating conditions to set a defined temperature and / or the following parts of the system against impermissibly high loads to protect.
  • An injection cooler known according to the preamble is from EP 0 682 762 B1 has become known and has been used in practice proven.
  • the object of the invention is a simple and inexpensive Alternative to the state of the art, with more compact Desuperheater design and optimal cooling water and To create vapor pressure control.
  • the desuperheater according to the invention has a water supply fitting with integrated cooling water control valve and one one or more nozzles connected to the feed fitting having nozzle tube protruding into the steam tube.
  • nozzles are simply constructed and work without any problems a spring-loaded nozzle pin with a cone tip, which with a Ejection hole cooperates.
  • the effective cone tip orifice area the acts on the application of cooling water Feather against and at the same time on the other, one The face of the nozzle pin forming the piston surface and acted upon by the steam pressure.
  • nozzles with different opening pressures equip so that depending on the steam pressure in the steam pipe and counteracting cooling water pressure one or more nozzles opened become. Because of these nozzles and the pressure ratios between Cooling water, nozzle and steam pressure is an optimal spray, i.e. a drop-free spraying of the cooling water for the Temperature control of the superheated steam has been achieved.
  • the Control valve can be carried out in one stage, because it is always sufficient Back pressure is present in the system.
  • the desuperheater for temperature control of superheated steam has a fixable on a steam pipe (1), such as flanged, Cooling water supply armature (2) and an outgoing and into it Steam pipe (1) protruding nozzle pipe (3).
  • the feed fitting (2) has the water pressure in the nozzle tube (3) adjusting control valve (4) and the nozzle tube (3) is with at least one depends on the water and steam pressure (P2, P1) adjusting nozzle (5).
  • the control valve (4) is designed in one stage and has an in Steplessly displaceable in the longitudinal direction of the nozzle tube (3) Adjustment rod (4a) with a throttle body (4b), which with one in the water supply direction (Z) behind the water inlet channel (6) the feed fitting (2) lying flow channel (7) interacts.
  • the flow channel (7) of the control valve (4) is in cross section smaller than the inner cross section (3a) of the nozzle tube (3) executed.
  • the nozzle (5) lies in the nozzle tube (3) transverse to the longitudinal direction of the Nozzle tube (3) and in the longitudinal direction of the steam tube (1).
  • the nozzle tube (3) is provided with several, e.g. With three parallel ones arranged at the same distance one above the other Nozzles (5) equipped, as Fig. 1 shows.
  • the nozzle pipe (3) is located in the steam pipe (1) (lower) end closed and the interior (3a) of the nozzle tube (3) sits up in the feed valve (2) up to Flow channel (7) out.
  • the nozzle tube (3) is in one piece with the feed fitting (2) is formed.
  • the feed valve (2) can by means of a flange connection (8) on the outside of the steam pipe (1) and the nozzle tube (3) with its nozzles (5) protrudes through one correspondingly large opening (9) of the steam pipe (1) in the same inside.
  • Each nozzle (5) has a nozzle which penetrates the nozzle tube (3) transversely Nozzle tube (3) fixed tubular nozzle pot (10), with at least one in the pot casing (10a) inside the nozzle tube (3) lying water inlet opening (11), one in the nozzle pot (10) under spring tension (12) and a nozzle pin (13) Ejection hole (14) pointing to the open one, out of the nozzle tube (3) protruding pot front end screwed on cap (15), the Nozzle head (13) with an end tip (16) with the Ejection hole (14) cooperates and the other from the bottom of the pot (10b) protruding end of the nozzle pin (13) one of the Vapor pressure (P1) acts on the piston surface (A2).
  • the tip (16) of the nozzle pin (13) is preferably from formed a cone.
  • the ejection hole (14) in the cap (15) forms one with the Nozzle pin tip (16) cooperating cylinder section to which an outwardly conically widening ejection section (14a) connects.
  • the nozzle pin (13) rests in the pot bottom (10b) adjacent, seals (19) arranged between thrust washers (20) guided and between a thrust washer (20) and the Guide collar (17) is a nozzle pin (13) towards the cap (15) pressure spring (12) acting around the nozzle pin (13) arranged.
  • the opening size and thus the spray pressure of the nozzle (5) will by the difference between the cone ring area affected by the cooling water (AR) of the area (A1) Injection hole (14) engaging nozzle pin cone (16) and the Vapor pressure (P1) applied to the nozzle pin piston surface (A2) Regulated depending on the cooling water pressure (P2).
  • nozzles (5) are arranged, they become formation different opening pressures designed differently; there can be used to set different opening pressures Ejection holes (14) with different diameters equip or the nozzle pins (13) can be different Have cone tips (pointed or flatter cones) or that Compression springs (12) are designed differently in terms of the pressure force or the nozzle pins (13) have diameters of different sizes.
  • the cooling water is through the control valve (4) in the Flow rate and thus regulated in the pressure (P2) and in the Nozzle tube (3) introduced and according to the design of the Nozzle (s) (5) build up pressure in the nozzle tube (3).
  • the cooling water flows through the hole or holes (11) in the Nozzle pot (10) and acts on the ring surface (AR) between Cone tip (16) and injection hole area (A1) and opens with smaller or larger stroke (H) of the nozzle pin (13) against Spring force (12), the nozzle (15) and the cooling water splashes to Steam reduction and temperature control off.
  • Example for the desuperheater When using three nozzles (5), the lower one has an opening pressure of 10 bar, the middle one of 15 bar and the upper one of 20 bar.
  • the nozzles (5) are arranged in the flow direction of the steam and spray cooling water in this flow direction; the Cooling water can also run counter to the steam flow direction be sprayed out.
